High-Pressure Differential Angle Regulating Valve
Category: Angle Regulating Valve
Product Details
Overview
- The valve features a simple structure, with the valve body's inlet and outlet arranged at a 90° angle. It boasts low flow resistance and high valve capacity, along with a wide adjustability range and highly accurate flow characteristics.
- Due to the angle-regulating valve's dead-corner-free flow passages and simple flow path, it features a "self-cleaning" function, making it suitable for applications involving high-viscosity fluids, as well as fluids containing suspended liquids and particulate matter.
- The angular regulating valve belongs to the single-seat valve category, featuring low leakage. However, since it retains the single-seat design, the allowable pressure difference decreases as the diameter increases.
- The flow path is simple and typically used for low-in, side-out configurations, which helps ensure better stability during regulation.

Features
The valve's throttling component employs a multi-stage pressure-reduction cavitation-prevention principle. The valve body features an upper-mounted design, while the valve seat incorporates a multi-layered, pressure-reducing sleeve structure that safeguards the valve body against damage caused by flash vaporization and cavitation. Additionally, the valve core and seat are built with ST alloy overlay welding, providing excellent resistance to erosion and wear. As high-pressure fluid flows from the inlet to the outlet of the throttling component, both its pressure and pressure drop gradually decrease in a controlled manner, effectively preventing cavitation and erosion. This valve is ideally suited for applications in the chemical, petrochemical industries, as well as scenarios requiring superior cavitation resistance.
